IMPROVEMENT IN ENVELOPES.

Specification forming part of Letters Patent No. 215,793, dated May 27, 1879; application filed September 11, 1878.

in Envelopes to Receive Novel Forms of Note- Paper, of which the following is a specification.

This invention relates to envelopes intended for the reception of note paper of peculiar forms; and it consists in the construction hereinafter more particularly set forth and claimed.

Figure 1 represents a blank of the envelope before folding. Fig. 2 represents the envelope folded.

A designates the back of the envelope; to a, the side flaps, b the top flap, and c the bottom flap. The top flap, b, is beveled on both edges near its junction with the back A, so as to vary its angle with the line of junction of said back, as shown. The side flaps,a a, have their upper edges inclined, as shown, and are triangularly notched at g, at the points of junction of their lower edges with said back A. These notches separate them from small corner flaps, h h, which are separated from bottom flap, c, by notches f f.

The aforesaid flaps all fold toward the center of back A, on the dotted lines shown in Fig. 1.

The envelope is above described with the flap I) uppermost for the sake of clearness, and because such is the position most naturally given'it in use. When folded, it has the form shown in Fig. 2, excellently adapted to holding note-paper with truncated corners.

I claim The combination, with the main part or back of an envelope, of side flaps, a a, having triangular recesses at their lower inner corners, angular corner flaps, h h, rectangular bottom flap, c, separated by angular notches or recesses from said corner flaps, and triangular upper flap, b, all of said parts being constructed sub stantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

ARTHUR GHRISTEY.
